A rough terrain crane is a two axle machine on large flotation tyres that drives around a site but not down a highway. Hire is operated and typically runs $1,500 to $4,000 for a day in the common capacity classes, plus transport on a lowboy in both directions, because the machine cannot deliver itself.
Why it exists beside the truck crane
A truck crane drives to site on the road and needs firm level standing. A rough terrain machine is built the other way round: poor access, mud, slopes and unfinished ground are its work, and it moves around the site under its own power with the boom rigged. The price of that is a haul truck at each end.
Outriggers, mats and the ground
The whole machine, plus counterweight and load, lands on four pads. Yards supply outrigger mats or crane pads, and on soft or made ground the pad size is calculated rather than guessed. Buried services, basements and trenches under the setup position are the failure everyone remembers, so mark them before the crane arrives.
Capacity classes and what they cost
Common hire classes run from around 30 tons to 100 tons. The number is a maximum at minimum radius, so a machine rated at 60 tons may lift a small fraction of that at the reach your load actually sits at. Bigger classes cost more per day and considerably more to mobilise, which is the line people miss.
What to have ready before the day
Load weights confirmed by the supplier, a set up position agreed, the route in checked for width and overhead lines, and somebody on site who can sign for the lift plan. A crane that arrives to find the position blocked still bills the day and the haul, which makes an hour of preparation the cheapest hour in the job.
Questions people ask about rough terrain crane
Can a rough terrain crane drive on the road?
Generally no. It is designed for site travel at low speed and is not registered for highway use, so it travels between jobs on a lowboy trailer. That is the main reason a short hire near a yard costs far less than the same machine two counties away.
How much space does one need to set up?
Enough for the outriggers fully extended, which is considerably wider than the machine itself, plus room for the counterweight to swing clear of anything behind it. The yard will give a setup footprint with the quote, and it is worth measuring on site rather than assuming.
Is a telehandler an alternative?
For placing materials at modest height and reach on a site, often yes, and it hires for a fraction of the price. It is not an alternative for a true lift with slings and a hook at radius, where the load chart and the crane are what the job needs.
